[Can I suggest followups go to Conculture; my active interest in physical
anth is mainly conculture-related, and has come up on that list before.]

It is of course true that the racial categories that most people operate
with are socially constructed and have scant empirical basis. But I
would like to query -- without necessarily disputing -- the assertion
that human subspecies -- in at least some relevant sense of that term --
don't exist.
I asked, on Conculture (iirc), for advice on reading in physical anthro
(especially on prosopography). The most pertinent advice I got was from
Brad Coon, who suggested the works of Carleton S. Coon [a very distant
relative, since you ask]. Off I went to our university library & found
in the very crap and unmodern half-shelf section of phys anth books that
the only really scholarly works were by Coon. I found them very impressive,
but I also had the impression that they were obsolete (though not that
obsolete, because Coon wrote the relevant entry in my 1989 edition of
Encyc Britannica) partly because they were written in the 50s and 60s on
the basis of then scant and cutting edge knowledge and partly because
what he claimed didn't square with my impression of the current received
wisdom. For example, he argues that Neanderthals are ordinary sapiens
adapted for an ice age climate. I found that on the face of things more
plausible than the current mainstream view, but then I haven't read the
rationale for the current mainstream view.
As for races, Coon argues that races antedate the sapiens species. His
idea is that erectus spread out through Africa, Europe, Asia, Australasia
and that through adaptation and drift there developed races, i.e.
statistically salient clusters of various biological features (not
including pigmentation, of course). An example is that there is a higher
incidence of carabelli's cusps in caucasoids (cusps on inside of molars
-- a maladaptive trait IMO, because the carabellis on my wisdom teeth
are sharp & often nick gashlets in my tongue). The sapiens species spread
not by the movement of people but by the movement of adaptive sapiens
genes, and these superimposed themselves upon the existing races.
At points Coon seems to hover on the verge of entertaining an idea that
some would judge racialist, namely the idea that racial differences might
include not just those that most people would judge trivial, such as
details of dentation, but also ones that people would judge significant,
such as 'intelligence' (perhaps judged by average cranial capacity, which
NB is used as a criterion of intelligence in distinguishing among hominid
and pongid species). For example, he sees the Caucasoid and Mongoloid races
as having developed in areas of great environmental diversity and high
genetic traffic, while the Australoid, Capoid and Congoid races didn't. He
suggests that the Caucasoid and Mongoloid races were therefore more
all-purpose adapted, and correlates this with the hypothetical spread of
Mongoloid dominance into former Australoid territory and also, iirc, with
greater average cranial capacity of the mongoloid race compared to the
australoid. (Needless to say, Coon does not to the least degree extrapolate
from empirical biological differences to moral and political issues about the
rights and worth of individuals.)
It's my impression that ideas like these are nowadays viewed as nazism
dressed up science. Me, I don't think that the idea that race has no
biological basis can be squared with who you see winning when you watch
the Olympic Games. The intellectual sin of biologically-founded racialism
is in judging people on the basis of their race (or even, arguably, in saying
individuals have a race). The moral sin of biologically-founded racialism is
in distributing people's rights on the basis of their biology.
I can well believe that Coon's theories have been superseded, but I would
be grateful to pointers to equivalently magisterial works that represent
the current state of knowledge and the empircal basis for it.
